Currently have -Xms set to 256MB and -Xmx set to 512MB, but that sounds low to me.
Not that I'm very experienced with such settings, but I "heard" that setting Xms and Xmx to the same value is recommendable and it was standard in the company I worked for. 256 MB is indeed not much, but 512 should be enough for normal Cocoon pipeline processing. Using FOP or Batik is more memory consuming.
